This message might leave you scratching your head, especially if your app works perfectly fine on iOS and in debugging mode.

Why Does This Happen?

AndroidX is a major improvement to the original Android support libraries. It provides newer and more efficient libraries that help enhance your app's performance and compatibility. If your Flutter project was created prior to the introduction of AndroidX or if it hasn't been configured correctly, this issue may arise.

Key takeaways regarding the problem:

Your project is missing necessary files needed for AndroidX compatibility.

Configuration issues related to Gradle can cause complications in building your APK.

Step-by-Step Solution

Don’t worry! The fix tends to be quite simple. Follow these steps to resolve the issue:

Step 1: Open Your Terminal

Whether you’re using Android Studio or Visual Studio Code, you’ll need to access the terminal. You can do this within the IDE or by opening a separate terminal window.

Step 2: Create Missing Files

To ensure that your project has all the necessary files, simply run the following command in your terminal:

Keeping your Flutter project updated and ensuring you have all necessary configuration files is crucial to avoid issues in the future. Flutter is a powerful tool that can help create amazing applications, and with a little troubleshooting, you can harness its full potential.
